I'd try the combo of seeds, cake, chocolate to make sure nothing clashes. Probably won't but you never know. Just be aware some people don't like seeds, just like some people don't like coconut because it gets in their teeth or they just don't like the texture.
I used a mix for a red velvet cake for youngest GD's birthday last week (her request) and it made a very, very soft crumb. Even cooled I still had to crumb coat it and let it set in fridge for several hours before adding final icing layer, gold. She wanted a "Loki" cake so she wanted his colors. They didn't dome hardly any because I wrapped the pans with wet towels but there was still a little. I did like bakechef, let them cool upside down, then put the two tops together and just filled in any gaps with icing when I crumb coated it.
