The orientation of the frog head might be a little off? I'm not sure, I squinting at your picture to make sure, lol!
I like where you're going with this, nice experimentations! I'm guessing you're practicing drawing animals accurately at the same time, good exercise!
Thank you everyone, I really appreciate it!
