these are looking better..however your not exploring enough. if you look at the exaple i gave you, each drawing is different and explores different ideas. The concepting phase is very important and exploring and doing things out of your comfort zone. THe gestures are looking good and has a nice sense of movement. Try to break out of your shell. Look at cool art and photos to inspire you. Reference is a super super important factor when it comes to concepting.
Good work!

demon silouettes

Here you have some silouettes, combining sketch number 10 with the membrane under the arms from sketch 12 :)

nice work!

Very cool thumbnails. Lets rewind a bit and worry about the characters shape. Lets try to do some silhouette studies. The shape is the first read of the character. Desinging within the shape is very secondary. Lets worry about the shapes first. Try to do solid black and white studies of the charcter the example shown. Go with the thumbnails you like so far and do mor exploration of the silhouette.
You can show gesture, proportion, shape language ( mainly using triangles, ciricles, squares etc)

First assignment!

Here it is my first assignment. It is thumbnails from ideas to design a demon. I've done 15 of them and I have lost the fear to fail, whic was something very usual for me, that's a good point. My favourites are 3, 7 and 12.
