Iced, they are of strong impact. I love the third for which I'll suggest the title "An arrow from the past". For the second I feel the same of min. The Dragon is the one I like less.
What are their size and which kind of surface are they made on?
It's a very good idea to restart to paint, to do creative things is one of the most relaxing and satisfying ways to pass free time.
Go on and please let's see all your creations.
Ciao, Sandro
