| Popping in for a visit are we?
Though I am a fan of Black and White yours don't really grab me, probably with better colors it could get better depth, especially the second.
The first... well I feel kinda neutral looking at it.
The second has some good effects but being in black and white it doesn't stand out much and needs to be drawn out.
The third I just don't like because of the render choice and effects.
The fourth has to much negative space but I like how the spatter brush and yellow light draw my eyes to face and mic. |
