Hi HappyPenguins! how are you? I gotta say i really like this picture, beautiful shading and i love the colors. I'm not too familiar with the show but I remember seeing them once in a while on tv when i was little and i gotta say, you really got their look and the feel of their environment thanks for sharing!
I like how you depicted each of them (like Fancy with the rose, Spook with the Cigarette, Brain.... yeah), but Top Cat should also be a ladies' man himself. I remembered how he helped Choo-Choo with his girlfriend [so I know he isn't gay (just saying because someone thought he was gay for some reason, maybe the purple vest)]. Any way, cool.
It's interesting to see a different style coming from you. I think it's great when artists can draw more than just one style. I like the streelight effect in the corner & the way the sky looks in the background. I've never heard of this show before.
