I love A and D actually, great work! D is really interesting and I like the victim, perhaps as a summoning focus? I love how big A looks, very intimidating. Out of curiosity, for that one are you planning on having the pile move with the character/ they ride it in battle?

Can't really pinpoint any special differences between each of the designs but D would be pretty sick as the summon

I think D is the most interesting for a zombie + spider combo, since one of the spider arms is a corpse, but if the character is a zombie spider summoner, I think C would be the best suited.

A + E with victims that look like the one in D.

So effing COOL!!!!
