Picasso goes to visit a kindergarten class. In the class he sees the children's artwork displayed. He's amazed at how great it all is. Just blown away at how such young children are doing such great art.
He asked the teacher, "How is it that all your student can create such fantastic artwork?"
The teacher responds, "I merely know when to take it away from them."
-- Half of good design is knowing when to stop.
Vertical type is a "no-no" and should never be used if it can be avoided. It's not "visually interesting" in my opinion and only serves to decrease readability, and often legibility. Much of "reading" is by shape. By using vertical type you eliminate that portion of perception forcing viewers to actually work to decipher the type - even if it's clear type.
Beyond that... the border under the type is acting essentially as a "strikethrough" on the type and is off-putting to me. If the type were horizontal, there probably would not be a desire or feeling that the strikethrough was acceptable.
Since I find this type placement and usage pretty bad I won't go further into the mix of sizes and spacing, which all could be addressed better in my opinion.
The slight grey page background tends to work best for me when there's also enough white on the page to show there's contrast, even just subtly, with it. There's not enough white in the photo or other elements to warrant the grey background. -- look at this site.. subtle grey backing with white in the "content" area. Without the white, the grey makes everything feel "muted" and "desaturated" even if it's not. One option could be to add white. Such as the inner matt of the photo frame. This "pushes" the photo off the background.
I think your border color is fine, it plays off of skin tones, but there needs to be more of it to work well. The border screams at the user because it's the only color element on the page except the photo. And shifting the border to match the blue background of the photo would help the border be far less prominent that it is. Or.. adding other color elements to the page which match the border color would also have the same effect.
Note the white matting added to the photo frame does a great deal to harmonize the border color with the photo in my opinion. The elements are seen as ONE item rather than a photo with a border offset from it. The white matting makes the border part of the photo, rather than a separated element, so the color works much better.
Text placement of the smaller blocks seems sporadic. Why are there different alignments, some left, some right? I would align everything left and move all text blocks to teh right of the photo. Or, align everything right and move it to the right side of the page where you have that bottom text block.
Or even with a more prominent name (tight leading was intentional)...
I just fall back into "Form vs Function". What's the function of the page? I assume, to get model information. Why then is the information as difficult to read and find as it could be? Make it all clear, centrally located and easy to read. In my opinion, good design shouldn't force a user to work to get the function of the design.
Sidebar: I have no clue how this web page would break out for responsive design. But I'm having difficulty envisioning any responsive adjustments which would be suitable. Unless elements are hidden/displayed based upon responsiveness.
