First of all: sorry if I don't choose the right words or my grammar is quite bad, but english is not my first language.
Congratulations for this great design here! It put a smile on my face just as I saw it. I really like how you made the head with a bigger shape and finish with a medium-small shape on the feet. I also like how the shirt and pants help to see the construction behind all the detail, which leads me to the next point: some parts are so detailed that you kinda confuse the viewer's eye. For example, it's hard to see the hand with the cigar and, in my opinion if you draw the scales only in the parts where the shadow is more intense, only marking them a bit more subtle on the light zones, it will help you to lead the viewer's eye where you want them to look. The eyes are a really important part, as they make you empathize with the character. I would appreciate a bit more contrast between the eye and the rest of the face, maybe using a brighter colour.
Another thing I would recommend is drawing the character with a clearer silhouette: take a bit more out the hand with the bottle, so you can clearly see what is he doing. I remember something a wise teacher once told me: the character's personality is defined a lot for whatever he/she is doing/holding with the right hand.
I think I'm not missing anything. I saw this character and it was so funny and well done that I had to comment. I don't want to sound rude at all, I just wanted to give a constructive criticism and I hope this helps you ^^
