i'm building a body where our design has failed

Now: Three of Wands. This card often heralds a time of beginnings, especially for things intended to be long-term. Often it's new projects of some kind -- wands are a very creative suit, so this goes double if it's some kind of creative project -- but it can also be some kind of a travel, a new opportunity, studying a new thing, even new relationships (not necessarily of the romantic kind). In general, if you're considering starting something new, I'd say this is a big "DO IT" from Linestrider, and if you've recently begun something, this may be a sign that needs to be your focus for the moment.

Later: Ten of Wands. I'd say this is likely tied to the state of newness in the Three, so I think it's talking about the same endeavor. On the one hand, this card is about completion of something -- but it can also be about burdens and taking on too much. Either what you're working on is going to end up being something very heavy on you, and you need to remember to take care of yourself and call in help when you need it; or you're going to be finding yourself at the end of it, and it may be hard to let go, or feel like you've put in a lot for less of a reward than you expected. It may still be worth it -- but it may not necessarily feel that way at the time.
