The grey bull with the flame horns (B) has way more attitude than the golden one, feels like it'd work on a streetwear drop rather than a finance client. Which way are you leaning yourself, and is this for a specific client or just portfolio exploration?

Nice. I like it

B, the flame horns win it

The grey one with fire horns, it depicts at typical bull, always fierce

it depends , what is the purpose for it? because if it is for a restaurant brand selling meat, A is the way to go, but for a game/mobile app, B will do it better; what is your personal scenario?

For an actual logo I would pick A. It reads as one clean silhouette that survives small sizes and single-color print, while B is a gorgeous illustration but the flame horns and shading will muddy the moment it shrinks or goes one-color.

Both can be used for different purposes. Choose A : if brand wants to show royalty or premium figure. Choose B: if it is something related to gaming, sports, racing related or anything other than premium show-off.

i think B is better with it's rude attitude, lols

Definitely B, love the detailed triangles and the blazing horns
