This is very well done and engaging. The colors are friendly without being typical, my one and only issue is that while the monster is very clear, the shadow on the left made me think scissors before clock. Perhaps make the different lengths of the bars more apparent. Also the highlight on the trash can may be a little bright, I think that is what's causing it to look like it doesnt belong

I had the same problem as Analise...First, I had no idea what the first shadow was and then I thought scissors...it wasn't till' after I read the first post that I was stunned to see that the shadow was implying the clock. So, I agree with that shadow rework, as well as, on the front of the barrel.
I'm not sure, yet should you use an "and" between "first" and "convenient" in that first title since there are less than three things referred to and we're not in the middle of some big term paper?
Overall, I love the monster and all that has been done in this piece.
