hey limitless,
would you be able to give us a few more renders from different angles?
From just looking at this current render that it looks like you could use a little more detail in the handle and more variation in thicknesses throughout the whole thing as the others have mentioned. but it is a very good start that's for sure, just keep tweeking, maybe check out more reference images about how thick certain parts of the gunblade should be, etc...
references are always a huge help, or they are for me anyways...
Unleash: sorry but the link you supplied doesn't seem to work :s the one concerning leigh van der byl's texturing site. (and yes it twas me that sent you the link
)
