Remember

'good job' and 'nice work' etc don't count as participation - we need two crits per assignment meaning 150 - 200 word each crit/analysis/objective writings on other student work

That adds up to about 600 words per week - I don't count words usually but I can 'eyeball' quantity and quality

I don't expect a thesis - pretend you are a boss or friend or art director commenting on something being shown to you - it can be casual and friendly but should be insightful - show us you have looked at the work - discuss line shape form texture space scale form movement depth overlapping tec...why you like, what works, and what could be improved. Onground I require two positive comments and two critical (not negative) comments.
