I like the first set of clouds you did but i think you did a better job on these! Dude i wouldn't worry about the timer, clouds are tricky to draw from a ref photo! to draw things well it takes time.
Ha! You should see some of the recorded times on my draws! These are fantastic! Exceptional really! One of the reasons I love to draw clouds is for the freedom it allows! I do start with a ref usually but I easily get lost in the sky and forget about the ref! Keep 'em coming! Can't wait for 3/3!
