The canvas is a nice size, and is stretched neatly over the wooden frame. The picture is nice, although not as sharp as it could be, and the colour is nothing like as vivid as the thumbnail picture suggests. I wouldn't go as far as to describe It as insipid, but it doesn't really dazzle. To be honest, the picture looks as if it has been enlarged a little more than the original resolution can handle, but from a distance it looks reasonable. Is it worth £25? Hmm.. Just about, I guess, but if you aren't on a budget, it may be worth spending a little more for something more substantial.
As a side note, it doesn't come with any fittings, so you'll need to buy some eye hooks and hanging wire, but I suspect many canvases are the same.. I've got one which cost nearly £80 which didn't come with fittings either, so it's not a price issue, but is worth bearing in mind if you're expecting to take delivery and hang it straight away.
