This is a very nice goblin image, provided in PNG format as both full colour and line art.
The licence for use is clear: that it may only be used in not-for-profit works and that the artist must be credited - and for once, it's stated clearly on the product page before you make a purchase, not in the download when it's a bit late to find out that the use you had in mind isn't permitted!
Anyway, he's a nice goblin, sensibly dressed in tunic and hose, with boots, a cowl and helmet and clutching a sword and shield. I used to have a PC goblin who looked pretty much like this in my mind's eye, maybe I should play him again!
The pre-coloured version gives him the traditional green skin, and the whole illustration is nicely-shaded - if you decide to use your own colourscheme on the lineart version, use it as an example.
