The viewer is instantly drawn by the details, perspective and color, all of which are well handled.
The image is filled with much detail, all of it well presented. The volcano dominates the image, as it should, the crown-like rocks around the caldera an effective addition. The green amidst the black ridges stand out together with the sinister red interior of the volcano and the surrounding clouds.
The perspective is emphasised by the ships, which are themselves well detailed. The impression of great height, looking down on a radically changing scenery is well highlighted. The image has great impact and vision as a result of these details.
Only one slight issue to raise, and this is possibly only a personal one. The volcano's texture suggests the digital artistry I've seen on older images, where it doesn't seem 100 per cent real. (I may just be imagining things).
The whole image is excellent and is certainly a standout to this viewer.
