Really good work. You have strong compositional skills. I love your seasonal house portraits so much I can't seem to pick a favorite. They remind me of Peter Poskas' work whose book is well worth the read. 

 On the subject of learning... I think learning new things is what keeps me interested in art. I speculate that maybe daVinci only did a dozen or so paintings because it became boring to him so he took his creative genius into other realms.

Happy painting! 

Hey, a fellow engineer turned artist - I really enjoyed your work, thanks for sharing.

"Unfortunately, I feel that I am learning things now that I should have learned a long time ago."

LOL. I've been painting forever and I still feel that I'm just now learning things I should have know all along.

Great work, thanks.

Regarding your statement "Unfortunately,...learning things now that I should have learned a long time ago": After years of feeling that way and having felt I'd wasted many years, I recently had the revelation that I've finally come of an age where my mind is open enough to really learn. It's been very liberating as a painter to discover that I can learn, grow, paint better.

The fortunate part is to be learning Now, instead of Never. One doesn't see many youthful painting 'prodigies'; if an artist is good they seem to continue to get better as the years go by.
