Looks fine to me, just off of resizing it. Also, the font is keeping consistency. I *can* change the tag line, since its technically not part of the crest. I might change that and see if it makes it look more interesting, keeping consistency but breaking monotony.
But I will cut out alternate versions an formats for different uses.
If you don't have Photoshop, get Paint.NET or GIMP. (recommended in that order)
They're free (& open-source) and they have high quality resampling, as opposed to that pixelation you get from other not as powerful programs like irfanview.
Never tried Photoscape. From the screenshots, it looks like something for ppl not knowledgeable in graphic editors like photoshop. Thats cool, I know some ppl I can recommend that to.
