Can I recommend adding a text at the top of that image that says something like "More effects in 'Pixel Fire Effects || FX'!"?
Without such a message, it was not very clear to me what effects were and were not in this package. I figured it out looking at the other page, but it should be clear from this page. Such a message will probably make for more effective advertising and prevent people from misunderstanding what they are buying at the same time.
(I'll probably buy both sets either way, so it's just a suggestion from my side, not a complaint)
