I'm not quite sure where to start here. You've got some really stellar pieces on display! Personally, I really like the lack of heavy saturation in your tags. It gives off a very distinct "you" style and it's a look I've just always preferred when making tags for myself. That said though, I would like to see more pieces from you that are out of your comfort zone! Play with heavy saturation, break out of the red/blue hues, add contrast like it's no one's business! Know what I mean? You're obviously not afraid to play with things like sizing, form, and positioning - so I'd like to see more experimentation from you. :)
Start with anything, I don't mind. I use that style because cartoon/anime/game renders seem to blend better under it unless in c4d lighting imo.
But yeah, that sounds nice. It's a bit of a rut and I've been experimenting with smaller style disruptions.
