I like your sketches a lot. Takes me back to the days when I did editorial work for Isaac Asimov's SF Mag and later at Amazing Stories (back in the 80s). I always enjoyed seeing the cover concepts and how they turned into the finished pieces -- all hand-painted back in those days.
Thank you - it's good to hear that! I've slowly come to the conclusion that I really prefer the older science fiction - with occasional exceptions, of course. The desire to steer my own personal art in that direction is very deliberate Chalk it up to "reminding myself why I liked this stuff in the first place"!
