By the way, that is the first tip on the guide I elaborated about the subject presented hereafter:
Guide For Not to Seem So Dumb While Describing a Picture
1. (As mentioned above) Be objective: do not imagine too much possibilities for what you are observing because the examiner may not be so imaginative as you are. What if he has never seen Pokemón?
2. Use a varied and suitable vocabulary: start with structures like 'There is...', 'There are...', or, if you are not so sure about something in the picture, just say 'It seems to be...', 'It appears...';
3. Explore the picture: try to compare it with another picture or situation, give your opinion about it, in other words, find something in it about what you can really talk, to demonstrate your oral skills;
4. Keep in mind that you may make some assumptions: not all images will be of an inkbolt, or as obvious as one. However, try to approximate your guesses to things of universal knowledge;
Observation: This is a guide in construction, so if anybody has any suggestion to improve it and make it more efficient, be my guest. Dumbs like me will thank a lot...
