My style is pretty much exactly what Sensei wrote, right down to the order of steps. Provided I have all the information I need, I start with identifying the episode, describing the scene, writing down my own personal thoughts on the cel, and then noting miscellaneous things like any oddities or damage to the cel.
For me, what I put up about the cel is equally important to the image. Because the series I love are relatively unknown (at least, on this hemisphere), it's definitely a goal of mine to be able to help others understand why I'm passionate about these shows. If I don't feel that I have the time to do a write-up, or that I'm not in the mood to where my words would do the cel justice, then I won't update. What this means though, is that I've been building up more of a backlog, since I keep buying but don't feel like writing about them.
On a side note, it drives me crazy to see cels on RS that don't have the cel information filled out, or obviously oversized cels marked as standard size...this probably makes me sound like an anal-retentive perfectionist, but no worries, none of this need for order seems to make it to the physical world.
