I am planning a full left arm sleeve. for my UPPER arm i already have a large black crocodile at the front. i wish to have a shark and a harbour seal to finish my upper arm with animals. anmd then for my FOREARM see this prompt 'arm sleeve tattoo design combining organic alien blackwork patterns and biomechanical dragon‑scale textures. Dense black sections flow around lighter geometric linework, creating contrast and movement. Incorporate fluid wave‑like shapes, layered scales, and textured shading to disguise uneven skin. Style: black and grey, high‑contrast, heavy pattern, scar‑cover design.” tattoo idea
