>>3054074Abstract is totally fine and I'm a fan of it also, but it needs to be more than "I don't know what I'm looking at". If you go the abstract route you need to add something to your composition to balance the confusion, something basic like symmetry or color that will hold the viewer's attention. Your flower photo has neither and doesn't make me want to look at it long enough to figure out what it is.
>I really like heavily grainy imagesYou should start shooting film then. Actually though, as you said in your deleted post, grain can always be added in post if you want it. Grain from a high ISO can't be taken away (without compromising other things) so you really should avoid it as much as possible.
