Another small step-by-step tutorial. This one is on how to draw canyons for your fantasy map. Didn't plan to submit this here, but it seems people like these kind of tutorials, so I thought why not . I hope you enjoy! cheers
for a top-down view there are loads of tutorials on www.cartographersguild.com. if you mean a birds-eye view of a city, this mainly comes down to a lot (and I mean a whole lot) of work. Tricky part with these is perspective, it has to be very tight to make it look believable. I usually use google sketchup to plot the most important buildings in 3d, chose a nice perspective and then export the bitmap to use for reference in Photoshop. Using that, I draw/paint each house the same way as the little tutorials I did. maybe once I have some time I can give a try to make a tutorial about that... cheers
I taught myself to do isometric cliffs (or a good imitation of), so I thought I'd just draw two opposite cliffs next to each other. It looks pretty bad.XD But the way you do it is definitely the better way to go.
