I have no idea how much work it would take to polish the designs so i wont ask for it but if it was simple and easy then polishing the weapon mounts would be nice.
Would actually be more work than it's worth!
I'd agree that it has less bulk than the MW4 model, but the Clan Mechs are rather fragile when compared to their IS counterparts, but on the other hand quicker, therefor I think the "slim" design of our model does a good job at displaying those attributes. Anything more bulky would only give you a false impression...
And about the "ears" they may seem a little small when compared to the MW4 model, but actually they fall in line with the slim design of the mech itself.
Aside of that there are two options on how to make them bigger;
1. make them part of the mech:
-would require new textures, normalmaps
-UV-map wouldhave to be redone
-trouble with variants that don't mount misslies there (Variant A and B)
2. create new weaponpods specifically for missiles on this mech
-would only be used on this particular mech
-need to build new model from scratch
both these options would consume more time than they're worth, considering that there is no reason but the look of the mech, to do it.
oh and let's not start about making the whole mech bulkier, that would mean a complete remodelling of the asset, in fact not going to happen!
