Day 262 and frustrations

My SIL’s cat passed away, so my brother asked me to draw him and his brother for him. One, the rotund one, is not so much a problem, but his brother is proving problematic. Just too angular so I cannot seem to capture his likeness…these are the ones I have been doing tonight in pen and ink, but it doesn’t seem to matter what medium I use. Hmmmm, maybe I should stick to strange felines.
