I love both as well! XD I lean towards creatures, since that's what I personally do the most of, but when people upload landscapes, it's like you're really seeing those worlds inside their heads come to life. Plus, I'm not so great with scapes yet, so when people upload them they fill me with awe! It's neat to see those who do both though, like you, but you also do human character design. It's cool to see how your style lends itself to each different 'genre'! I still don't understand how you're so amazing at all three, you're magical
I love seeing both from artists! Landscape designs can be just as interesting as a good character design, and in my opinion every artist (who is interested in both) should practice their skills in each one. You need something to put your characters inside of right?
I love both! Though I guess more specifically I should say I love characters as much as landscapes assuming it has... well, character. So portraits and scenes are awesome, but concept art doesn't usually do it for me unless the character is still really expressive.
