Hm not sure where to start...I'm just in love with your art!
Well firstly, I noticed immediately that you have a beautiful sense of balance and design. I feel that each organism is placed with such pose and the background does a great job of supporting the subject.
Secondly, your technical skill is nothing short of stupendous.
You also have the mind of a creative artist, not just a scientific illustrator's deathly accurate drawing skills. It is quite reassuring that you don't have photo-realistic work, but instead original and creative works in your own beautiful style!
I noticed you don't have any recent works..but I beg you to keep posting, as the person below has said. Keep up the great work!
