Here are a few pics of my Moro beast in progress. It's actually all together; I'm waiting for the black acrylic primer to dry before I start painting. (and I'm also going to do a touch of research since I'm going to paint the fur similar to an African Wild Dog.)
Next, I drilled holes in the allosaur head and gorilla body and dry-pinned (with a large brass rod) the two parts to get the position I wanted. I glued the head to the body (with the pin) and started to fill in the large gap with green stuff. Another layer of green stuff was sculpted into fur. I impressed divots into the fur where the spines would be placed. I decided on spines but left off a feathered head crest; I think there's already enough going on at the front of the model.
I tried a lion-type tail (with brass rod and a greens tuff tuft at the end), but it just wasn't doing it for me. I think a slightly larger tail would fit fine and balance the model well, but adding tails simply made the beast look too conventional; I'm looking for slightly more freakish.
Paint comes tomorrow. And I should be able to finish him this weekend - of not tomorrow. I'm happy with this quick, off-the-cuff conversion. I have a few more old, second-hand dinosaur toys sitting around in a footlocker that I think just became a larger bits box.
