I like this one. Its not your usual titan that I have seen. It has this retro lego robotic look. Impressive.
Btw, I am personally inviting you to join in the Bionicle Display(formerly the Bionicle Flagship Display) 2nd Triathlon Contest. There are three interesting challenging categories for you to join. Join one or better yet join in all. The best mocers will try to give their entries. It can be a learning experience for you while having fun. For details visit:
My SECOND favorite mecha, Ryan Tennant's Mistique in second, and Yuri's Shiva in close second, very nice job on the overall design, looks a bit like something I'm working on, but I guess it's always harder to work with just technic and system XD anyways, nice job.
