Thanks for the feedback SquarePug and Liberado, I'm glad people are liking the assets. It Looks set then, I'll have to do some effects, I might also put a voting system on the site so I can find out what assets are needed in general.
I totally agree with you about OGA it's a great site, but seems that most of 2d sprites on there are pixel art style, in fact that's why I don't bother putting pixel art on my site, OGA has it covered already. and I prefer to stick to one style for the moment.
I'll let you both know when the effects are done, although there's a few things that I'm working on at the moment.
