You, right, looks better with improved texture of the gun part. Also, agree with the "reality point of view", and will consider it in furher models, but this one will be ok, because guns aren't supposed to fire simultaneously, but one after another, so the load won't look excessive.
Strange, I thought it's possible to add some transparency in "Opaque" blend mode, but it didn't work. So, had to use "Alpha Add" mode, and it appeared like this. So, looks like I like the non-transparent one a bit more.
yeah, I thought about but had to to watch polygon count, so there is nothing left to pull to locally expand the stem... but I made leaves' stems a bit wider where they originate from the main stem, so it look a bit more realistic now
btw, its impact effect will also look like a flower, but will be made of flame and explosion effects :)
