I am creating a web app and I have got several questions about its appearance, first here's a "screenshot" (just a test with Pixelmator):
The element in the center is a flashcard, the arrows on the right and on the left let the user browse the cards.
Do you think that the flashcard looks like a card? How can I improve the "card feeling" while keeping the appearance as simple as possible?
Do you think that it's a good idea to keep the arrows white? Or should I use the same black than the other elements on the top? (I have chosen a white color because I think that these arrows are more linked to the card than the other elements, is it right to do that ?)
What do you think about the fact that I am not using the same font for the card and for the UI? I am doing that because I think that a serif font is more appropriate and that It helps to distinguish the text of the content. And also because I think that it might help the user to remember of the word more easily.
UPDATE (here is a new version, I followed the advice of Jenna and now the cards are displayed as a stack, and also added a letterpress effect to the words on the cards):
