A couple of weeks ago, I bumped into some sort of art block as to not knowing what to do next. I was inspired by Alien Isolation back then; played it, dropped it, played AvP instead and watched Covenant. Towards the end of that time, I had the idea of deigning a Xeno character, but this theme was quickly dropped as other projects demanded to get attention.
These four sketches initially were some warm-up studies of the Xenomorph, which I had never drawn before. My goal had been to draw one of these finished concept sketches a day... which had worked for 4 days as you can see and then I had to work on some character design.

I never planned on putting them up here but as I revisited them today, I really grew to them and among my pals, they found appeal as well. So I decided to put them in a collection to make up for their rather low quality.
There have been made some deliberate choices in their design, I removed these back-pipe-things and revisited different themes to put them in. It is also worth mentioning that this sketching method brought me to develop a new approach to my projects, which found really good use for my last artwork.

I hope you enjoy these for a change. And please tell me what you think about them and which one is your favourite.
The row in which these were made is starting from the top left and moves clockwise.
