Nude life drawing classes

We're a group activity booking website that sells experiences for stag (bachelor) and hen parties and other celebrations. One of these activities is nude life drawing classes, which is particular popular with female groups, for example for a hen party.

This is a fun and light hearted activity, not aimed at serious artists, but is for a group to get together and try something different, with an art instructor to give them tips, champagne to enjoy during the activity and a nude model for them to sketch - generally male groups sketch a female model and female groups sketch a male model.

We're looking for images to represent this activity in a tasteful way, so no full nudity is allowed and it should ideally show people taking part in the activity enjoying themselves and looking like they're having fun, but in a neutral space (the activity is done in various venues). If people are shown in the photos then they need to be single sex groups - ie, if it is a male group then everyone taking part in the sketch needs to be male drawing a female model and vice versa. Typical group size for this activity is around 12, but this is obviously difficult to set up, so an image that shows 2-3 people taking part but gives the impression of a larger group would work too. The attraction for many groups, is the nude model, so this can also be a focal point of the image.

Image must be landscape, 3:2 and min 2560px wide.
