I'm not too great at this. It's my first time trying actually, but it's pretty easy actually.
All together it took me about 2 hours on each picture
I'm not completely done, I want to try and shade it in to make it look more like the picture..
Grid off your picture into even squares. Then do the same one a blank sheet of paper that you intend to draw on. Make sure you draw your grid on your drawing paper lightly with pencil so you can erase it later.
Take your drawing one block at a time. Try drawing what is in the first block on the actual picture into the first block on the drawing paper.
Keep repeating step two, only in all the different boxes on your drawing paper. make sure what's in the boxes match up.
Color and shade as you wish.
I'm not too good at shading so I didn't attempt too much.
Yours will probably come out better =]
Erase the grid lines on the paper when your done
