I agree with Roland that it looks like a plains-cow under the fog. It also looks like there is a hint of grassland-green W-NW, and under the forest W-SW, and definitely SW-S-S.
A coastal start with the unit ticks removed makes me think portugal is a strong possibility for our tribe, so seafaring/expansionist.
My worker will move west to reveal the max. number of tiles, and also to get closer to the cow, which will likely be the first tile he develops. Unless my worker move reveals something surprising, my settler will move one NW to settle, to benefit from the cattle early, and also from the possible grasslands to the W-NW. If the worker move does reveal an interesting bonus, I may chose a different location if we are not seafaring. If we are seafaring, then settling any tile other than NW will be most unlikely.
