Design Task: Tentacle Creature

Because of how often they are used in fantasy, sci-fi and horror, this weeks task had us study tentacles, and our homework was to design a tentacle creature. The first thing I did was compile some research into a small moodboard, which comprises of real tentacles, how other artists draw them, and how they are used in the video game media:

From this I did some practice in my sketchbook, first I practised with the tentacle shape (top-left), and I think they look authentic and successful, then I drew a Zombie Diver (bottom-right) from an idea I had based on one of the research images. I then drew a Sea Warlock design, using tentacles as not only their legs but also their "hair", I like how this design looks in terms of how much more dynamic it looks, so I'll be digitalising that. lastly I did 2 more practise tentacles (bottom-right), one with fangs and another with colour, the coloured one doesn't seem to have a good colour scheme but then again I was experimenting:

Here is the final concept image:

Because I did not have a lot of time to work on this, I didn't get the chance to practice digital painting, and as a result I resorted to a quick form of shading.
