I entirely agree with WhyDoIdIe

you have a good base , now it's polish in every domain :
better 3D models , and fight with real bad guys , not poor ones on the street !!
a real story , real stages/bosses, and
fluid animations : no standing robots

, but better moves.
same thing for graphics, polish them , but i know that the art of texturing
is really really deep and need lot of work to master it , but with some work you
can produce great things , and a tips : use homogenous textures, not too bright
ones , or too dark.
A big tips for your level : draw it with a tablet, colorise it with light colors and draw all objects , textures :
after that you'll have a precise idea of your level and textures :it's like
Pro games : all games serious in game industry are made with 2D art illustrations : prince of persia 3 , god of war etc ....
like WhyDoIDie said
keep it , polish it , first try to find a modeler to make some better 3D character in better resolution , caus you don't fight 10 persons ,and it's not
big levels like mmorpg , so use better resolution characters.
For animation try , to make more fluid one , realistic, a tips perhaps :
use Mame arcade emulator, run street fighter or double dragon 5 or another one
like SNK series or final fight , perform moves and pause game to capture screenshot and try to make same moves with your characters.
perhaps you'll have more fluid realistic and smooth animations , have you used animation blending ?
for camera, why not keeping a travelling one with soem 3D zoom or rotation in some case ; like in GOd of War on PS2 (the best action/adventure game of all time

) !!
I think it would be a lot better , play God Of War and perhaps you'll change yoru mind on the camera ?
yes, it's a game bad compared to final fight on mame or double dragon
, final fight 3 on Snes , or other great beat them ump.
Keep working in it

caus lot of us could buy it if oen day you reach commercial quality

take your time , if you plan a year that's good , so go slowly ,but surely,
and why not use bump shader on characters later

?
