welcome!! that is an awesome first draw! a few tips...make your canvas a little bigger...it helps not to have to squish everything in there...nice job on the sky...maybe a little more shading on the ground...shadows and such...but very nice!!!
i believe you can only do that at the beginning when you pick the applet...at the very bottom left...itll have the dimensions and you can change um...i dont think you can change it for this one tho...
