I've been trying to draw a beehive graphic in illustrator. My approach has been to draw an ellipse in yellow and change it's perspective. Then on top of that adding a copy of that ellipse, resize it slightly, make it black and place it over the first yellow ellipse so it forms a banana like shape. I do this slowly getting smaller all the way up to the top, alternating yellow and black where I finish with a full ellipse. This approach has been working and the result I get is good but I've found it hard to make the beehive a uniform shape all the way up....simply adjusting the size of the ellipses by hand means that I end up with uneven gaps of black between the banana like sections and slightly uneven banana sections.
Any ideas on how I can draw this with more accuracy? I'm very new to graphic design.
I've attached an image that was taken with a mobile phone of the screen. I drew the image at home and took a picture for a friend. I'm now away from my computer so don't have access to the original image - hopefully this will give you an idea of the problem though.
