Yay...

I like it very much, thank you.

Responding to your request for critique...

Firstly, regarding your concerns about the red building, I think it was actually a great choice. Light grey would make the colours feel too muted, I think. The perspective isn't really too big of an issue here given the framing and the position of the character, and what is present works fine. :) Though you may want to reverse the way the letters on the main building narrow (wider towards the ground and narrower towards the top, rather than the other way round) since it looks like you're going for an upshot.
From the standpoint of the figure I've got no real qualms, though her arms look a bit short even with perspective in mind. You could afford to lengthen both the upper arms just a smidge.

Other random notes: The edge by the sidewalk feels...lacking. Maybe a couple trees would help it? Or a railing to indicate it's by some water? Also, regarding the overall feel, I think being much bolder with your shadows would help this tremendously. Since she's so gigantic she needs to be a commanding-feeling presence, and presently she feels kind of weightless. You started to put some shadow on the building she's sitting on, but I think casting the majority of that building in shadow would really showcase the weight and mass someone of her size would have.

A fun badge overall; a good concept, solid colouring, and a good sense of scale and proportion. :3 I also rather like the way you draw trees.

Hope this all helped!

THank you a lot for your input! I didn't even think about the effect having more cast shadows would give--what a great idea! I will definitely keep that tip in mind for the future =) Yea, the edge of the sidewalk is weak. It just kind-of ends. Originally I had drawn in telephone poles to show more perspective but they really skewed the view and looked bad, so I removed them, but I should have put something back to take their place.

I wasn't sure about the building either, when I first drew it, it was in proper perspective but I thought it would add a little bit of character to have the building narrow at the bottom. I think the horizon line falls somewhere in the middle of the building, which made it look funny when I just narrowed the top. I think it might actually be more fish-eyed, but wasn't sure how to pull it off.

Arms are one of my weak points, you're right, if I straightened those they wouldn't reach her thigh really. I also think one of them is broken XD

Thanks again for taking the time to write me a very helpful critique, I'll think about applying some of the tips you gave =)

No problem! :3 Thank YOU very much for taking the time to respond!
