tinytreats -
I think your soap will be lovely once it's cured. It looks like it's going to very bubbly and I'd like to hear what you think of the lather. However, it might take several weeks longer than normal to harden because of the high percentage of castor. When did you make the batch? BTW, some people have commented that they experience some stickiness in soap with a higher castor amount.
I don't think it will be too drying for normal skin. I have dry, sensitive skin and I generally use coconut at least 25% with a higher superfat. The palm oil isn't going to add dryness because of its mildness in cleansing. I like the look of the recipe Cake Baby posted and you might want to give it a try. It looks like it would be a mild soap with creamier lather but not as conditioning as your recipe. Nothing wrong with being less conditioning - Cake Baby's recipe is similar to what I make as a body soap.
Another recipe I would suggest to give you slightly different results.
Castor oil 10%
Coconut oil 25%
Olive oil 40%
Palm oil 25%
If you have dry skin, you can use a higher superfat. I normally use 7%-8% but it wouldn't be a problem to use even higher - 9%-10%. You also might find Zen Soaps single oil page interesting since it gives a good idea of what an individual oil adds to a batch.

BTW, hot process may be "ready" to use in a week but there's more going on during the curing process than just water evaporation. Week old soap can be drying but becomes milder during the curing process and the lather becomes better. As an experiment, slice a bar into sections and try a section after a week, another after 2 weeks, another after 3 weeks and another after 4 weeks. You'll most probably find a difference between one week and 4 weeks. To be fair, there have been a couple of people who have mentioned their recipes are as gentle in a week as they are in 4 weeks but normally most recipes require longer curing.

I just thought of other variations of your recipe which would up the conditioning a little bit.
Castor oil 10%
Coconut oil 20%
Olive oil 40%
Palm oil 30%
Castor oil 10%
Coconut oil 20%
Olive oil 50%
Palm oil 20%
This recipe has the same values in cleansing, conditioning and hardness as your recipe. But olive does eventually cure hard while castor doesn't. So, it wouldn't require as long as a cure as your recipe. You can add 2%-3% ppo of sodium lactate to help with initial hardening to get it out of the mold sooner.
What makes a good recipe is really personal preference. Experimentation is important to find out what you prefer so you might want to make several batches for comparison.
I thought you meant my reply. Actually it's good to point out that soft isn't a good term to use. Someone wrote a better explanation about exactly what "hardness" means when discussing soap but I couldn't remember who wrote the post. If I get time to browse, I'll try to find it because it was interesting and would be helpful for clarification.
