The feet are good: simple but effective. They work better than the default method of attachment for that type of foot and look good as well. The model in general is awesome actually. I think I might use that foot design in one of my own creations. The weapon is epic; Vakama's disc launcher, Kalmah's feet, & Ackar/Tahu(stars)'s sword flame: nice!
I love that foot design, I wish I'd thought of that (I actually used that design in one of my MOCs, and it was one of my favorite features of it). Have you ever thought of making the fully-mutated Hordika? I think you could do that really well
I've considered it, but one of the main reasons why I haven't done that is because I'm trying to keep my gallery as unique as possible - I avoid Toa-sized humanoids when I can, and I generally aim to make things which haven't been done before.
That's a very vague question, but I'll do my best to answer XD
I generally start with a concept, then try to visualise what would work best in terms of pieces. Then I work out how to connect them without getting in the way of other pieces, and voila! Done. Bear in mind that the Flame Titan is definitely not a good example of this, though It's far too simple compared to the more recent things I have in my gallery.
i'll give you that one i've seen you bionicles......only if i were to have them when i was little. XD oh the memories....sorry XD but yeah there was this one bionicle i saw you made it was like a mix of your heroes. now that one was badass.
