A little off topic--- Question on shadow

[Raxial]

yeah, well I haven't tried drawing/coloring any fan art yet, but I usually just draw like buildings/ things around buildings (without computer aid since i never had a scanner) I just use regular #2 pencils and occasionally a colored pencil [I prefer black and white, i screw up freehand coloring]

anyway, i just didnt think the shadowing on this one looked right. what's off, if you can say

I did both of those about a year ago

PS: sry if that's a little off topic, in all fairness though it's about shadowing really
