a really good exercise when trying to define your own style is to go through the gallery here (or at a few different sites to get a broad range of styles) and just put everything you ADORE into your favourites list. Do that for a week or so. At the end of this time, go through your favourites list and keep only maybe your top 20. Then decide from looking at those - what is it that you like about them so much? do they have anything in common? a common style? designers? use of elements? clustering? simplicity? Then try scraplifting a handful of those (and the people who made them will be HONOURED you scraplifted them - give credit of course).
My gallery isn't much to speak of either... but I always find I like the result better when I had something I wanted to communicate with the layout in mind and was successful at communicating that (a feeling, emotion, a story, etc.) and I'm slowing learning some design principles that make me happier with the finished product.
some of these things I'm learning (and others might disagree here....)
1) triangles are visually appealing - three major focal points in your layout are better than two or four. These can be a photo and two flashy elements, etc.
2) don't be afraid of white space - it's powerful, and don't be afraid to have elements, photos, journalling pieces, etc. 'touch'. Overlaping them and clustering them together is often visually appealing.
3) make what you do look like it was done on 'purpose'. So if using 'white space - large blank areas on your layout' make them BIG, otherwise it looks like something is missing.
4) contrast is important - two different alphas together should be very different, use lots of contrats of colours, textures (like sticker elements with felt ones, buttons and fabric, paper and flowers).
I like your gallery a lot - you've tried some really bold things! You'll be happier with your results after some practice!
