I've been playing around with Inkscape quite a bit, but the one thing I've always had a problem with is getting anything I make to look realistic. It all seems to come out looking cartoony.
One such case was when I was trying to make concept art for a piece of furniture on a certain online game.
This is the item I made:



The first thing I made was just a very basic (and extremely unrealistic) tentacle. I then did tons of raster effects on it until I thought it looked somewhat better. I still wasn't at all happy with it, so I tried just scrapping the whole thing and starting over after looking at a bunch of pictures of octopus tentacles. I think you'll agree the 3rd picture looks the best, but honestly, it still is lacking the realism I would like it to have.
Does anyone have any ideas? Maybe a way to make the tentacles look textured in some way? Perhaps change the stroke?
If you'd like the .svg file for the tentacles, let me know.
Thanks very much,
Kyle
