I gotta say Buggi, your pictures are so good for how long you've been painting...really.
I probably wasn't even born when my dad started so I never saw his early stuff but he always said, it was 10 years before he thought they were good enough to sell..I guess you are your own hardest critic.
Is there anyone in your family that showed the same skills ?...my grandad was a master carpenter who also dabbled with a canvas, dad and his twin brother became self employed artists, my elder brother and myself always had a pencil in our hands and I can copy stuff, but don't have the ability to create something from nothing. I tried painting years ago and while I thought they were ok for first attempts, I lacked the drive to continue it..something I occasionally think may have been a mistake.
You're enjoying it, you're good so keep going....if that's what they're like now, imaging what you're capable of as your skill grows.
