Haha yeah, they're all visible to me now. Thank you for taking the trouble of uploading them again! o/; Anyway, let us get started, shall we?
Firstly, I don't know if you're using GIMP or PS. I'm not really familiar with GIMP and its features, to be honest. But still, to me, it seems like you've used the 'lighten' blending option in most of your tags. Although almost all of them have flow, what they really lack are good effects. They just don't seem to fit. Miku tag..it looks like you just put a flowing render over her and tried using some blending option. Instead of doing that, you could've put some c4d behind her or in front of her, blurred/sharpened it or tried some sorta texture or something. Some really awesome resources are available here in the resource threads in G&P itself. You might try using those to spice up your tags. Really, the miku tag is kinda bland with no depth, weird colors, weird lighting (the lighting at the top-right corner is too over-powering, imo) and lack of spicy effects. As far as the tag with BW pokemon (idk his name) goes, the main problems with it are pretty much the same as with the Miku tag.
Now moving onto your 'better' works...

^ that is pretty good. I like the effects (although slightly messy) used and the colors are fine too. But yeah, the opacity of the c4ds below giratina's face and above its 'claw/hand/wing/tentacle' at the bottom-right side is weird. I would've preferred it if you had erased some parts.

Out of your tags, this is, by far, your best. I'm sure you know that as well! XD; But yeah, simply duplicating a render and placing it alongside the main render isn't really a good practice. I tend to do that too, but I kinda resize it a bit so that the duplicate layer is either a miniature version or a bigger version of the original. XD; What it needs is perhaps a little more effects? Text placement..umm, I won't comment on that. Text placement tend to be a very hard job on most tags anyway. I'd advise you, like someone awesome advised me a little while ago, that you make two versions of every tag you make. One with and one without text. You can post both the versions in your gallery. ;)
Oh and yeah, that green circle thingy at the left side looks kinda iffy. It doesn't really fit the mood of the entire tag. But I'm assuming it was a part of the stock/render, yes? Also, stay away from low quality images. They end up ruining the whole tag. Okami, at some places in the tag, looks low quality. Try to go for HQ images when searching for stocks.
Anyway, that's it from me for now. Hope I didn't go horribly wrong in my crit. I'm not really good at this anyway. :<
